To all ladies who have commented and those just reading…emails and calling 1-800 numbers may only get you so far. I actually took time to write a formal letter to Johnson and Johnson as a class project in school and was sent all types of samples and a really nice letter in response. Try it old school and you may at least get a good coupon if not samples of many types. BUT, you have to be nice in your letter to them not acting as if you are owed something. Tell them you’ve used their products for years, or know of those who have and that you are interested in trying certain items, your due date….if they had promotional item(s) you could try. Boost their EGO and they might boost you with gear/samples. Just throwing it out there – Good luck!
In 2018 the company launched its newest diaper line called Pampers Pure which was designed without chlorine bleaching, fragrance, lotion, parabens, natural rubber latex and 26 allergens identified by the European Union.  The wipes launched with the new collection contain 99% water and premium cotton. Pampers announced that the goal was to give parents an option for an affordable natural diaper brand. 
There are several different organizations around the country that distribute free diapers to needy and low income families. Many of these are charities or churches, with some government programs also assisting. There are programs for single mothers, teenage moms, and families living in poverty. Anyone that needs free or low cost diapers near where they live, and that meets qualifications, may apply.
